North Atlantic Upper Ocean Temperature Profiles from DOLPHIN Cruise

North Atlantic Ocean temperature-depth profiles collected using a Mechanical Bathythermograph (MBT) aboard the DOLPHIN from June 25 to 30, 1969. Data is processed into the NODC C128 standard format, providing paired temperature and depth measurements at uniform 5-meter intervals. The dataset captures the thermal structure of the ocean's upper layers to a maximum depth of approximately 285 meters.

Use Cases

• Analyzing the vertical temperature structure of the upper North Atlantic Ocean for a specific week in 1969.
• Studying short-term thermal variability in surface waters using time, date, and position data for each profile.
• Calibrating or validating ocean mixed layer models with in-situ temperature-depth value pairs.
• Investigating instrument characteristics and data standards of historical MBT observations in the C128 format.

Strengths

• Data is processed to a known standard format (NODC C128), ensuring consistent structure.
• Provides precise temporal coverage for a specific cruise from June 25 to June 30, 1969.
• Temperature measurements are recorded at uniform 5-meter depth intervals, facilitating analysis.

Limitations

• Key metadata is missing or conflicting: row count, column names, file size, and license are unknown across all sources.
• Data is limited to the upper ocean, with a maximum observation depth of approximately 285 meters.
• The dataset represents a very narrow time window (6 days) and geographic scope from a single cruise.
